On June 4, KLA Corporation fell 3.67% in regular trading, trading at $2056.27/share, with trading volume of $152 million. Earlier in the session, the stock had broken through its prior 52-week high to reach $2108.0 before the broader semiconductor equipment sector experienced concentrated profit-taking pressure.

The pullback came after a sustained rally driven by multiple positive catalysts, including Bernstein raising KLA's target price from $1875 to $1975 and lifting global wafer fabrication equipment spending forecasts to $148 billion (a 21.4% year-over-year increase), alongside KLA's announced 1-for-10 stock split plan. However, elevated short-term trading congestion triggered concentrated selling as funds locked in gains. The semiconductor equipment sector declined broadly, with Applied Materials down 3.59%, Lam Research down 4.55%, ASML down 2.59%, Teradyne down 4.1%, and AXT Inc down 0.92%.
